6.4 Power On/Off Control
The power switch on the device is the main switch for power on/off
control. The main power switch is turned on during initial installation of
the device.
For easier handling, you can use the power button on the front left of
the Vanquish system base (system power button) for power on/off.
Observe the following:
•
All modules in the Vanquish system that are connected to the
system base via system interlink cables are turned on or off
simultaneously when the system power button is pressed.
•
When the power is on, the system power button is pressed in. When
the power is off, the system power button stands out.
•
If the main power switch on a device is off, you cannot turn on the
device with the system power button.
•
To turn off a device completely, you have to turn it off with the main
power switch on the device. Pressing the system power button will
not be sufficient to turn off the power to the device completely.
Upon power up, the device performs a self-test. If the self-test is not
successful, the status indicators are red and the device is not ready for
use. Check the Chromeleon Audit Trail for the related message and take
appropriate remedial actions.
At the end of the power up, the device sets the fraction collection valve
to waste position and needle unit to home position. If the compartment
door(left) is open, then the needle unit moves to parking position to
leave customers manual operation space.
